Yes it does look like that. Probably have it then.

So, the injector stuff. I have 5 brown Bosch 373cc 0280156023 injectors. Looking through HP calculator at 4 bar fuel pressure, it tells me they are capable of 308 crank HP. If I'm looking a bit higher, say 350, what would be the best injector kit for me?

[Morris400]

Rs2 injectors or rep Rs2 injectors (Bosch 37lbs). Or you could go Bosch 440 (green giants) to give some head room.

Like these? http://www.ebay.com/itm/NEW-Green-Gi...-/171217050412

I thought they would cost a lot more...

What about the turbo? Stock K24 wont pull 350 wheel HP, and it's leaking oil a little, so turbo change will happen at some point. Which would be better suited for my app besides RS2 K26? Looking at 034 offers, since I don't know any quality local shops.

Look into efi express or iroz motorsport. They have billet k26 options and also have a billet k24 that is in testing but said to be good for 300+ ish whp maybe more. I believe there is also a rs2 billet option but I've not look much into it. For my car is a daily driver and I'll be keeping my stock turbo. I've got a spare k24 - 7000 just incase my current one dies.

[RichLV]

Have I found the correct injectors?

Didn't find anything at EFI and Iroz requires me to have a good turbo core, to send back after I buy their turbo, which I do not have.

I wish I could keep the stock one, but it wont last long, it has axial forwards/backwards movement of about 1mm, so it's inevitable to change it sometime in the future.

[Morris400]

Rs2 rep injectors, had a set of these but traded for a clutch lol.

Green giants ( on this page but there is a fall and short version, not sure which one fits.)

Understood, thank you.

Intercooler? Read somewhere that stock one flows good enough for 500 or so HP. Or do I need bigger front mounted one?

[Morris400]

I wanted to do a front mount too but the Oem smic is good to 350.ish. no need really untill big power.

[RichLV]

Cool. Less expenses then ))
Thank you, you are very helpful.

[RichLV]

Does RS2 turbo pack enough to safely take it to 350HP? Or the hybrid KKK/Garrett units are better?

[prj]

The 373cc will be sufficient (barely) for the RS2 turbo, no need to buy other injectors if you already have these.

[RichLV]

Thank you prj, always good advices! RS2 turbo with these injectors would solve some inconvenience issues. With RS2 turbo I don't need custom oil and water lines, and K24-7200 is more accessible. So the baseline right now is:
1. RS2 exhaust manifold (new)
2. RS2 K24-7200 turbo
3. Bosch brown 373cc injectors
4. I suppose a 3 bar MAP will be necessary
5. Maybe I'll throw in 7A exhaust cam if it will be available
6. A remap, ofc.

Sounds good for 350HP?

[RichLV]

Some updates from the car.
Massive exhaust renovation, will be remade from scratch starting from downpipe.
New fuel lines will be installed, old ones have corroded badly.
Some sill welding will take place.
Got new front shocks!

And finally oil is gonna be changed in gearbox and diff.


GOT IT!! Was surprised how cheap it was - 35 eur.

My boost hoses have cracked recently and I'm looking for silicone replacements. Are ebay chinese any good? Like these for example - http://www.ebay.com/itm/Silicone-tur...item3f28f81312

If not then I'll order 2 lower hoses from Sweden. Sweden sounds like more quality if chinese aren't worth the money.

I've heard that ebay hoses are good, John (newsh) on here said he used ebay hoses for his IC and he runs RS2 setup 2.0bar and it's all good.
